T 0 all whom it may concern":

Be it known 1-. CHnrs'rorrmn. DONIGAN, a citizen of the United 'States' and a-rcsident of Newark, county of Essex, and State of New Jersey, have invented certain newiand useful Improvements in Heels, of which the following is a specification,

This invention relates to annnproved heel made ofresilient materiahaisually rubber-, which can be quickly attached" and detached,

and which can thus bemadeinterchangeable from one shoe to another,-so"that when worn on one edge the heels can 'be' intcrchanged so as to cause wear on the other edge. he invention relates further to a heel four points of excess wear can be utilized.

The invention also-relates to a heel of th1s form of foot. weakness. Y The invention is illustrated taching means Figure 2 is a section through aheeland the heel portion-of a shoe'.-*Fig-" ure- 3 is an enlarged detail SGCtlO'ILOftL' partof a heel and an attaching means. Figure 4: is a perspective View illustrating one way of releasing the heel from the shoe,-andFigure 5 is a top View of a form of heel different from that shown in Figure l.

The heel is designated by the reference numeral 10 and may be made of any suitable resilient material, and I prefer to use rubber, now commonly used in heels, and to secure a maximum of resiliency the heel is usually made entirely of rubber. The nature of the material provides an easy cushion effect when the heel is trod on in walking, and the resiliency also permits a lateral compression of the heel, and particularly it permits a somewhat extensive local distortion or compression of the heel where attaching means are secured. This is utilized in yieldingly holding catches or the like in holding or looking position, and also permits their intentional displacement from such locking position so that the heel can be removed.

One form of attaching means is illustrated in the drawing, which shows a series of catches 11 which are in the form of pegs and which project from the top face of the heel and extend with hooked portions or people with this;

- tom part of. the shoe at the heel inany suitable manner, usually by nails or pegs driven throughholes 17for. the purpose, the heel can beiattached b'yisimply pushing it: against the plate eiioughto cause the catches '11 to ride over the edgesltl and the hooked in the accom panying drawing, in wh ch Figure 11s a'per spective view of a heel and one form of'atlieved, and the material assumes itsfnorrrial shape when such lateral pressure is relieved; These catches lliare usually provided with a shank 13, anda broadened head ll isiplaced engaging ends 12 which project outward. radially, that is, toward the outer edgeof! the heel so that they can be moved laterally,r thus subjecting the :material: atthis pOin-tto a slight distortion, which, of. course,-is reon the inner end and,'being embedded' i-nthe 1 material of the heel, provides for a positive I holding of the peglor latch 'inflth'e heel. It

will beevident that these. catches: can be caught over properly disposed holding edges,

and in the form shown Ip-rovide a plate l5 preferably in the form of a frame which has on its inner; edge the parts 16 which are spaced apart in conformity with the spacing .ofthe'catches 11...

It will" thus be evident that when the plate 15 is fastened tox'a shoe,'eithertoone of the upper layers o-f'a heel or to the .bot-

in position. 7

To prevent lateralflstraiiron the'pegs in any excessive degree, I prefer to' useanchor ing devices, which may 'be in the form of lips 18 which project down 'in similarly disposed recesses 19 in the heel, although any similar or equivalent means for so anchoring the heel. against lateral movementcan be employed.

lVhen the heel is tobe removed it-can be done by the insertion of'an element laterally along the top edge or face of the heel and the pegs successively disengaged, pressing them radially inward, and 1n Figure 4 ll show a convenient method of movlng them inward'simultaneously by means of a thin wire or cord 20 which is crossed and then pulled in the form of a closed loop along ,the top face of-the heel, and such wire or cord will then take the: position shown in lligure 3, and when tightly pulled will pull all the pegs radially toward the center, as

shown in said figure, and the heel can be lifted away from the shoe.

To act as a positive guide andprevent the destruction of the wire 20, I prefer to place a marginal flange '21 on the edge of the plate 15, whichserves'not only to more securely hold the plate against lateral movement, but

also to provide a positive means for guiding" the wire 20 between the plate '15 and the top'face of the heel.

' In Figure 5 I show atop view of a heel of a norma form with the pegs 11 disposed for attachment of such shape of heel to a shoe.

The form of heel shown in Figures l, 2

and 3 is designed'for the purpose of being placed end 'it'orend onthe same shoe when uneven wear is to be-coinpensated "for, and also to'serve as'a shank support.
